Stewardship

Mugwort (Artemisia vulgaris) is abundant and cultivated globally. Used in moxibustion and dream work. Stewardship: Eden's position: we honor the plant's long traditional use without adopting the divinatory practices; the plant's terrain actions are Creator-given.

In the traditional record

Mugwort (Artemisia vulgaris) — known in medieval European tradition as "St. John's girdle," worn as a protective belt on the eve of St. John's Day (June 24); referenced in the Anglo-Saxon Lacnunga manuscript as the "oldest of worts" (eldest of herbs) and used in TCM as Ai Ye for moxibustion.

On our sources

These entries draw on public-domain materia medica, most of it published before 1900, alongside a smaller number of modern reference works. Energetic qualities such as warming, cooling, drying and moistening are a traditional framework for describing how a plant behaves in the body, not a laboratory measurement. Where a period source states one, we cite it. Where none does, and for many North American herbs none exists, the value reflects modern herbal consensus rather than a historical text. When we cannot support a caution with real evidence, we say nothing rather than guess.
